Sorry, I missed the "X11 session" part. Bug confirmed.
** No longer affects: gsettings-desktop-schemas (Ubuntu)
** Summary changed:
- Onscreen keyboard is disabled by default
+ Some shell elements don't respond to touchscreen in Xorg sessions
** Changed in: gnome-shell (Ubuntu)
Importance:
Looks like it's been disabled for at least 6 years:
https://gitlab.gnome.org/GNOME/gsettings-desktop-
schemas/-/blob/master/schemas/org.gnome.desktop.a11y.applications.gschema.xml.in?ref_type=heads
so whether or not it gets toggled automatically is probably up to gnome-
shell.
